My daily driver Audi 1.4 with full BCB running gear

I am preparing for 288mm brakes as well 👍

I wouldn't expect any major difference as piston diameter is the same as FS-3. Just little bit more "leverage" because of the bigger diameter and more meat for heat to dissipate and therefore more time before fading occurs.

288mm are a big difference to standard. With Willwood you can do stoppies.
 
Cloth TT seats installed today . Go well with the TT steering wheel

@celsisone - How did you get on with finding someone to remap the Magneti Marelli ECU? Was there a particular type of software they needed to do the work, or did you just do a lot of phoning around?

I spoke with my local Audi / VAG tuning specialist ADS (well known nationally) but they couldn't work with something so old.

I'm about to start my own BCB swap journey. First decision is whether to buy a £250 engine off eBay and get it to the local engine shop for rebuild, or to buy a running donor and wish I had more drive space.

No , you need an AUS engine. Comes in the early mk4 golf’s, bora and seat Leon’s .

Have been seaching for an AUS engine for an AUA potential replacement for future-proofing. Drawing a blank right now. BCB available in UK. AUS only available from overseas with very high transport charges. Reading the AUA>BBY & AUS>BCB threads in various different sites, is a BCB swap for an AUA definitively impossible? The available information suggests that transfer of all bolt-on ancillaries would be essential, as well as dealing with something related to crank-case breather arrangement that is different on AUA, but otherwise should then run on AUA ECU with the cognate 4-way coil pack.

Correct me if I’m wrong but isnt the aus 102ps??
Not sure of that idea of fitting a heavier 1.6 if your sticking to na and aiming for 120 horse is worth the effort?
I read earlier was stated 11kgs between engines?
iv driven both bad and aua and it feels like more weight then this for some reason. The 1.4 is really sweater then the other engines to hussle point to point.


What you would be more effective is getting an aub 100ps 1.4 ecu from a Fabia, unlocking it by “immo off” then fitting it along with an aub inlet manifold, all of this is easy to do.

It would take it up from 75 to 100 brake.. and it would rev much better because of the less restrictive inlet and increased redline to 7k… would totaly wake up the aua with no weight penalty over the front axle.

Four branch manifold, decat and closed air intake… mapping in those mods in would unlock more power possibly 10-15 buf ponies

And some cat cams would get you to 125

A bit of weight reduction( 85 kilos by bench seat removal, rear crash bar, smaller battery and pepperpots ) would make it a nice drive ! Especially for direction changes!

With you all the way but rear crash bar removal? Is that hypothetically speaking or track use only scenario?
@enzo, your next assignment should be a real world 'head to head' comparison of the BCB and AUB when fitted in the A2.
🙂👍
EDIT
The change of direction in a non AC 1.4 is impressive. I can safely take corners faster in the petrol compared to the TDI as is rolls about and looses grip.

Remember the start of the game Gran Turismo and you are limited in funds so get to choose between a lightweight Yaris or MX5 and slowly build up the mods and hone your driving skills, well the 1.4 non ac petrol is akin to that.
This take me back to hours of fun.

I’m not descussing fitting an aub engine

Just the inlet .. tb and ecu from an aub onto an aua

And yes removing the weighted crash bar from underneath the rear bumper..

It’s dead weight to me and one of the first things i remove when I get my hands on an a2

I might enter the project world in the very near future! I'm 50% certain I'd like to give it a go with a 1.6 and 50% on 1.4 petrol.

The 1.4 balance with non-OSS and non-ac was very good, so may tip it. To be honest although I do like formula 1 I'm no Lewis Hamilton so perhaps the lower powered 1.4 is the way to go!

Final choice may easily be down to availability of a donor car, and timing. 😃

Volk Rays 16" 7.0jj SE37K 5.0kg each waiting in the wings. JOM blueline and adjustable droplinks, and my newest purchase 2x Sparco Rev Plus at 6.6kg each or 7.1kg with current padding. Should be a nice saving on standard front seat weight est. 25-30kg total TBC

Hi, do you think just a aub manifold and ECU will give you 33% increase in power?
It seems unlikely but maybe you’ve done it.

Yes , but you need to change the complete loom and clocks to run polo gti engine .

If I wanted to do that . I would just fit a 1.4tfsi unit .

I needed a stand alone ECU to run a polo gti engine and a loom to suit. It is not for the faint hearted. It’s a fun engine and box but if I was doing another conversion I’d go BCB.

I am fitting an after market ECU emerald K6 unit to my rover 220 turbo.

As for the A2 I still this the best and easiest conversion is BCB 1.6 .

I hope to have the 1.8 turbo car later in the year . But think that will end up just being used on the track .

Yea aub inlet tb and unlocked ecu would get you to 100ps

These screens are taken from a Spanish forum where 4 guys have done this modification

An extra 25-30 horse for very little outlay on an na engine is pretty good. The aub is 100ps from the factory

It does have slightly different cams and injectors if you were being anal about it but it’s proven to work
